You would have something like this, using lumped models:
gap k12 k23
+--o o--+ +-----+-----+ +------+
| | | | | | |
C1 L1 L2 C2 L2' L3 C3
| | | | | | |
+-------+ +-----+-----+ +------+
This circuit behaves exactly as a "magnifier", where instead of a direct
connection from the top of L2 to the base of L3 there is a transformer
L2'-L3. I have done an analysis of this configuration, and didn't see
particular problems, or advantages. A set of design formulas can be
derived from the design formulas for a magnifier:
I can post the formulas for this configuration, if there is interest.
C2 can be omitted, and then the circuit is equivalent to a regular Tesla
coil with a different link between primary and secondary, but then
parasitic capacitances at the connection can't be absorbed.
